Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to data collection methods and apparatus. Background Technology

[0002] 3GPP (3rd Generation Partnership Project) Release 19 launched a work project (WI): "AI (Artificial Intelligence) / ML (Machine Learning) for NR Air Interface," supporting network-side model data collection and UE (User Equipment)-side model data collection. The collected data includes measured channel information, such as L1RSRP and / or beam ID. For network-side model data collection, it supports the UE performing measurements and recording based on network-based measurement configurations and reporting the measured channel information to the network. For UE-side model data collection, it supports the UE performing measurements and reporting the measurement information to an OTT (Over-The-Top) server or a UE-side data collection server.

[0003] Since the specifications of AI models may exceed the scope of the 3GPP protocol (except for the reference model used for performance calibration), the specific implementation of AI / ML training and AI / ML inference may be determined by the hardware equipment vendors themselves. It may be based on classic models such as Transformer structure, RNN (Recurrent Neural Network), CNN (Conventional Neural Network), or a hybrid model composed of multiple models. Summary of the Invention

[0004] Data collection plays a crucial role in model training and / or inference, directly impacting model performance and usability, and consequently affecting system performance. Therefore, ensuring the continuity and consistency of data collection has become a pressing technical challenge.

[0005] To address the aforementioned problems, this application provides a solution. While the measurement configuration used for data collection during model training is described above as an example, this application is also applicable to other measurement configurations, such as network optimization, achieving similar technical effects. Furthermore, adopting a unified solution across different scenarios helps reduce hardware complexity and cost.

[0006] To address the aforementioned technical problems, this application discloses a method used in a first node of wireless communication, comprising:

[0007] Receive a first information block, wherein the first information block configures a first value for a first timer;

[0008] Receive a second information block, the second information block including a first measurement configuration, the first measurement configuration indicating at least one RS resource;

[0009] The first timer is started or restarted in RRC_CONNECTED, wherein the start or restart of the first timer depends on a MAC SDU being sent or a MAC SDU being received;

[0010] When the time elapsed since the start or restart of the first timer reaches the first value, maintain RRC_CONNECTED;

[0011] Wherein, maintaining the RRC_CONNECTED depends on the first measurement configuration; during the time interval from the start or restart of the first timer to the elapsed time reaching the first value, the first node neither receives nor sends any MAC SDU.

[0012] In existing technologies, when the dataInactivityTimer expires, the UE enters RRC_IDLE, thus affecting the configured first measurement configuration. The above method maintains the RRC_CONNECTED state according to the first measurement configuration, avoiding any impact on the first measurement configuration.

[0013] According to one aspect of this application, maintaining the RRC_CONNECTED depends on a first process being performed; the first process includes performing measurements based on the first measurement configuration.

[0014] This technical solution further clarifies that maintaining the connection state depends on the first process of performing measurement based on the first measurement configuration, and provides the preconditions for maintaining the connection state when the time elapsed since the start or restart of the first timer reaches the first value. This is beneficial for continuing to perform measurement based on the first measurement configuration and avoids affecting the first process.

[0015] As an example, the first process performs the measurement based on the first measurement configuration.

[0016] As an example, the first process involves performing measurements based on the first measurement configuration and reporting the measurement results based on the first measurement configuration.

[0017] As a sub-example, the first measurement configuration includes a measurement configuration solely for data collection from the UE-side model. This method facilitates continued data collection for the UE-side model, improving the efficiency and performance of model training.

[0018] As a sub-example, the first measurement configuration includes a measurement configuration solely for data collection from the network-side model. This method facilitates continued data collection for the network-side model, improving the efficiency and performance of model training.

[0019] As one embodiment, the first process includes performing a measurement based on any one of a plurality of measurement configurations; wherein the second information block includes the plurality of measurement configurations, and the first measurement configuration is any one of the plurality of measurement configurations.

[0020] As a sub-example, the plurality of measurement configurations include measurement configurations for data collection only for the UE-side model.

[0021] As a sub-example, the plurality of measurement configurations include measurement configurations for data collection only for the network-side model.

[0022] As a sub-example, the plurality of measurement configurations include measurement configurations for data collection for the UE-side model and measurement configurations for data collection for the network-side model.

[0023] As an example, maintaining the RRC_CONNECTED includes: continuing to perform the measurement based on the first measurement configuration.

[0024] As an example, maintaining the RRC_CONNECTED includes: not stopping the measurement performed based on the first measurement configuration.

[0025] According to one aspect of this application, the method in the first node includes: stopping the first timer during the first process;

[0026] During the first process, the first timer is neither started nor restarted.

[0027] When performing measurements based on the first measurement configuration, this technical solution neither starts nor restarts the first timer, and it also clarifies that stopping the first timer is performed concurrently with the first process, further laying the foundation for the continuity and consistency of data collection.

[0028] According to one aspect of this application, maintaining the RRC_CONNECTED dependent on the first process being in progress includes: maintaining the RRC_CONNECTED if the first process is in progress; wherein, the time elapsed since the start or restart of the first timer reaching the first value means that the first timer has expired.

[0029] This technical solution maintains the connection state when the first process is in progress even when the first timer expires, providing feasibility for the continuity and consistency of data collection.

[0030] In the above method, when the first timer expires and the first process is not in progress, the process enters RRC_IDLE.

[0031] As an example, when the first timer expires, if the first process is in progress, the first timer is not indicated to expire to a higher layer.

[0032] As a sub-implementation, when the first timer is instructed to expire to a higher layer, the process enters RRC_IDLE upon receiving a notification of the first timer's expiration from a lower layer.

[0033] As an example, when the first timer expires, the first timer is indicated to expire to a higher layer; when the first timer expires from a lower layer, if the first process is in progress, the RRC_CONNECTED is maintained.

[0034] As a sub-implementation, when the first timer expires as received from a lower layer, if the first process is not in progress, the process enters RRC_IDLE.

[0035] According to one aspect of this application, the method in the first node includes: receiving a third information block, the third information block configuring a value for a second timer; wherein the first process includes the second timer being in operation.

[0036] This technical solution describes the first process in the case where the second timer is running.

[0037] As an example, during the operation of the second timer, a measurement is performed based on the first measurement configuration.

[0038] As one example, the second timer is a MAC sublayer.

[0039] As one embodiment, the second timer is an RRC sublayer.

[0040] As an example, the second information block and the third information block belong to the same RRC message.

[0041] As one embodiment, the second information block includes the third information block.

[0042] As an example, the second timer is started when the second information block is received.

[0043] As a sub-implementation, the second information block indicates the start of a measurement based on the first measurement configuration.

[0044] As an example, when a signaling is received, the second timer is started; the second information block belongs to an RRC message, while the signaling does not belong to the RRC message.

[0045] As a sub-implementation, the signaling and the second information block belong to two different RRC messages.

[0046] As a sub-example, the signaling is a MAC CE.

[0047] As a sub-implementation, the signaling is a DCI.

[0048] As a sub-implementation, the signaling instruction initiates the execution of a measurement based on the first measurement configuration.

[0049] As an example, the second timer is stopped when another signaling is received.

[0050] As a sub-implementation, the other signaling instruction stops performing measurements based on the first measurement configuration.

[0051] As an example, when the first node detects an RLF, the second timer is stopped.

[0052] As an example, the second timer is stopped when a cell handover is performed.

[0053] As an example, the second timer being running means that the second timer is started and has not been stopped and has not expired.

[0054] As one example, the first process not being performed includes the second timer not running.

[0055] As an example, "the first process is in progress" means that the second timer is running, and "the first process is not in progress" means that the second timer is not running.

[0056] As one embodiment, the first process includes the second timer running, and the first process also includes a specified time during which the second timer is not running.

[0057] As one example, the specified time during which the second timer is not running includes at least a portion of the time before the second timer starts.

[0058] As an example, the specified time during which the second timer is not running includes the time during which the second timer is paused.

[0059] As an example, when the second timer is configured, the statement "maintaining RRC_CONNECTED when the time elapsed since the start or restart of the first timer reaches the first value" is true.

[0060] As a sub-implementation, if the second timer is not configured, when the time elapsed since the start or restart of the first timer reaches the first value, the process enters RRC_IDLE regardless of whether the first process is in progress.

[0061] As a sub-implementation, if the second timer is not configured, when the time elapsed since the start or restart of the first timer reaches the first value, if the first process is in progress, entering RRC_IDLE includes stopping the measurement based on the first measurement configuration.

[0062] According to one aspect of this application, the method in the first node includes: entering the RRC_IDLE state when the first timer expires; wherein the expiration of the first timer depends on the time elapsed since the start or restart of the first timer reaching a second value, the first value being different from the second value; and the first node has not received any MAC SDU and has not sent any MACSDU from the start or restart of the first timer until the first timer expires.

[0063] This solution defines the first timer as expiring when the elapsed time of the first timer reaches a second value, and the first node neither receives nor sends any MAC SDU from the start or restart of the first timer until the first timer expires, which is beneficial for compatibility with existing protocols.

[0064] As an example, when the time elapsed since the start or restart of the first timer reaches the first value, a first signaling is sent; when the first timer expires, the process enters the RRC_IDLE state.

[0065] As a sub-implementation, when the first timer expires, it indicates that the first timer has expired to a higher layer; as a response to receiving the expiration of the first timer from a lower layer, it enters the RRC_IDLE state.

[0066] As an example, when the time elapsed since the start or restart of the first timer reaches the first value, the first timer continues to run.

[0067] As an example, when the time elapsed since the start or restart of the first timer reaches the first value, no action is triggered.

[0068] As an example, when the time elapsed since the start or restart of the first timer reaches the first value, the first timer is not indicated to expire to a higher layer.

[0069] According to one aspect of this application, when the time elapsed since the start or restart of the first timer reaches the first value, a first signaling is sent.

[0070] This scheme sends a first signaling message when the first timer reaches the first value, which can promptly inform the network and enable the network to have a more comprehensive understanding of the terminal status, thus providing the possibility of improving system performance.

[0071] As one embodiment, when the time elapsed since the start or restart of the first timer reaches the first value, the first timer is indicated to expire to a higher layer; as a response to receiving the expiration of the first timer from a lower layer, if the first process is in progress, a first signaling is triggered.

[0072] As one embodiment, when the time elapsed since the start or restart of the first timer reaches the first value, the first timer is indicated to expire to a higher layer; as a response to receiving the expiration of the first timer from a lower layer, if the first process is in progress, a first signaling is triggered, and if the first process is not in progress, RRC_IDLE is entered.

[0073] As one embodiment, the sending of the first signaling is triggered by the expiration of the first timer.

[0074] As one embodiment, sending the first signaling includes triggering the second signaling.

[0075] As an example, the first signaling is an RRC message.

[0076] As an example, the first signaling is transmitted via DCCH.

[0077] As an example, the first signaling is a UEAssistanceInformation message.

[0078] As an example, the first signaling is at least one field in a UEAssistanceInformation message.

[0079] As one embodiment, the first signaling indicates that the first timer has expired.

[0080] As an example, the first signaling indicates that data is available.

[0081] As one embodiment, the first signaling indicates that there is available data, and the first signaling also indicates that the first timer has expired.

[0082] As an example, one field of the first signaling indicates that there is available data, and another field of the first signaling indicates that the first timer has expired.

[0083] As an example, the other field indicates that the reason the first signaling includes the first field is that the first timer has expired.

[0084] As one example, the second signaling includes measurement results.

[0085] As an example, the second signaling is an RRC message.

[0086] According to one aspect of this application, the method in the first node includes: sending a first measurement report, the first measurement report including measurement results for the first measurement configuration; wherein the radio bearer carrying the first measurement report is a DRB; or, the radio bearer carrying the first measurement report is an SRB, the identifier of the SRB being 4 or greater than 5.

[0087] This solution promptly reports the first measurement report, providing a feasible feedback mechanism for data collection over a period of time, especially network-side data collection over a period of time. This avoids the terminal discarding some of the collected data due to various reasons, and facilitates the acquisition of better-performing AI models.

[0088] As an example, the measurement results for the first measurement configuration depend on the first report configuration; the first report configuration is associated with the first measurement configuration.

[0089] As an example, the measurement results for the first measurement configuration are stored in the first storage unit of the first node.

[0090] As an example, the first storage unit is a UE variable.

[0091] As an example, the first storage unit is an AS buffer.

[0187] As an example, the second node N02 is the network-side device of the serving cell of the first node U01.

[0188] As one embodiment, the second information block includes the first measurement configuration and a first measurement identifier, the first measurement identifier indicating the first measurement configuration, and the at least one RS resource being associated with the first measurement identifier.

[0189] As one embodiment, the second information block includes multiple measurement configurations and multiple measurement identifiers, the multiple measurement identifiers respectively indicating the multiple measurement configurations, and the at least one RS resource is associated with the multiple measurement identifiers; the first measurement configuration is one of the multiple measurement configurations, and the first measurement identifier is one of the multiple measurement identifiers.

[0198] As a sub-implementation, when instructing the first timer to expire to a higher layer, the process enters RRC_IDLE upon receiving a notification of the first timer's expiration from a lower layer. In this method, when the first timer is not instructed to expire to a higher layer, no expiration notification is received from the lower layer, and therefore RRC_IDLE is not entered, thus maintaining RRC_CONNECTED.

[0199] As a sub-implementation, the time elapsed since the start or restart of the first timer reaching the first value means that the first timer has expired. In this method, when the first timer has expired, the first timer is not indicated to a higher layer for expiration, thus reducing cross-layer indication overhead.

[0200] As a sub-implementation, when the time elapsed since the start or restart of the first timer reaches the first value, the first timer has not expired. In this method, if the first timer has not expired, it is naturally not instructed to expire to a higher layer.

[0201] As an alternative embodiment, "the first timer has not expired" means that the remaining time of the first timer is greater than 0.

[0202] As an alternative embodiment, "the first timer has not expired" means that the first timer is not running.

[0203] As an additional embodiment, "the first timer has not expired" means that the first timer is in a paused state.

[0204] As an example, when the time elapsed since the start or restart of the first timer reaches the first value, the first timer is instructed to expire and be sent to a higher layer; when the expiration of the first timer is received from a lower layer, the RRC_CONNECTED is maintained; wherein, the time elapsed since the start or restart of the first timer reaching the first value means that the first timer has expired.

[0205] As an example, the MAC entity of the first node indicates that the first timer expires to a higher layer; the higher layer is a protocol layer above the MAC sublayer.

[0206] As an example, the first node instructs the first timer to expire to a higher layer at the RRC sublayer; the higher layer is a protocol layer above the MAC sublayer.

[0207] As an example, the RRC entity of the first node receives the expiration of the first timer from a lower layer; the lower layer is the protocol layer below the RRC sublayer.

[0208] As an example, the first node receives the expiration of the first timer from a lower layer at the RRC sublayer; the lower layer is the protocol layer below the RRC sublayer.

[0209] As one embodiment, the higher layer includes an RRC sublayer, and the lower layer includes a MAC sublayer.

[0210] As an example, maintaining RRC_CONNECTED means not entering RRC_IDLE.

[0211] As an example, maintaining RRC_CONNECTED means: not performing the action of entering RRC_IDLE.

[0212] As an example, maintaining RRC_CONNECTED means not entering RRC_IDLE or RRC_INACTIVE.

[0213] As an example, maintaining RRC_CONNECTED means not performing the action of entering RRC_IDLE or RRC_INACTIVE.

[0214] As one example, maintaining RRC_CONNECTED includes: not resetting the MAC.

[0215] As an example, maintaining the RRC_CONNECTED includes: continuing to perform the actions in the RRC_CONNECTED.

[0216] As an example, maintaining the RRC_CONNECTED depends on the first node being configured with the first measurement configuration.

[0217] As a sub-implementation, the first measurement configuration is configured at least on the first node U01, and the maintenance of RRC_CONNECTED is performed.

[0218] As a sub-example, if the first node is not configured with the first measurement configuration, the maintenance of RRC_CONNECTED is not executed.

[0219] In specific implementation, during the time interval from the start or restart of the first timer to the elapsed time reaching the first value, the first node neither receives nor sends any MAC SDU.

[0220] As an example, the time elapsed from the start or restart of the first timer reaching the first value means that the first timer has expired; the time interval from the start or restart of the first timer to the elapsed time reaching the first value means the period during which the first timer is running.

[0221] As an example, "the first node neither receives nor sends any MAC SDU during the time interval from the start or restart of the first timer until the elapsed time reaches the first value" is used to determine that the first timer has not been restarted.

[0222] As an example, during the time interval from the start or restart of the first timer to the elapsed time reaching the first value, the first node does not experience a radio link failure (RLF).

[0223] As an example, during the time interval from the start or restart of the first timer to the elapsed time reaching the first value, the first node does not undergo cell handover.

[0224] As an example, during the time interval from the start or restart of the first timer to the elapsed time reaching the first value, the first node does not receive a signaling instructing the first node to enter RRC_IDLE, or the first node does not receive a signaling for connection release (e.g., RRC_Release).

[0252] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to this application, as shown in the attached diagram. Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture for control plane 300 is illustrated using three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 layer will be referred to as PHY301 in this document. Layer 2 (L2 layer) 305 sits above PHY301 and includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. It also provides security through encrypted data packets and cross-area mobility support. The RLC sublayer 303 provides segmentation and reassembly of upper-layer packets, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat Request). MAC sublayer 302 provides multiplexing between the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell.

The radio protocol architecture of the user plane 350 includes Layer 1 (L1) and Layer 2 (L2). The radio protocol architecture in the user plane 350 is substantially the same as the corresponding layers and sublayers in the control plane 300 for Physical Layer 351, PDCP sublayer 354 in L2 Layer 355, RLC sublayer 353 in L2 Layer 355, and MAC sublayer 352 in L2 Layer 355.

[0260] Example 4

[0261] Example 4 shows schematic diagrams of a first communication device and a second communication device according to this application, as shown in the appendix. Figure 4 As shown. Figure 4 This is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in the access network.

[0262] The first communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0263] The second communication device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0264] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting lost packets and signaling to the first communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and mapping of signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based and non-codebook-based precoding, and beamforming processing, generating one or more spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. Multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmitter processor 471 into an radio frequency stream, which is then provided to different antennas 420.

[0265] In the transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any spatial stream destined for the first communication device 450. Symbols on each spatial stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper-layer data and control signals transmitted by the second communication device 410 over the physical channel. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of Layer 2. The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer data packets from the core network. The upper-layer data packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing.

[0266] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, a data source 467 is used to provide upper-layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions at the second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the second communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0267] In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the receiving function at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as computer-readable media. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides multiplexing between the transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper-layer data packets from the UE 450. Upper-layer packets from the controller / processor 475 can be provided to the core network.

[0372] for First node U01 In step S7100A, maintaining RRC_CONNECTED depends on the first process being performed, which includes: if the first process is being performed, maintaining RRC_CONNECTED.

[0373] Wherein, the time elapsed since the start or restart of the first timer reaches the first value means that the first timer has expired.

[0385] As an example, maintaining the RRC_CONNECTED includes: not stopping the measurement performed based on the first measurement configuration.

[0386] In one embodiment, the lower layer is one of the MAC layer, RLC layer, and PDCP layer. In another embodiment, the higher layer is the RRC layer.

[0387] In one embodiment, the lower layer is one of the MAC layer, RLC layer, and PDCP layer, and the higher layer is the RRC layer or is located above the RRC layer.

[0388] In one embodiment, the lower layer is the MAC layer and the higher layer is the RRC layer.

[0389] As an example, when the first timer expires, if the first process is in progress, the first timer is not indicated to expire to a higher layer.

[0390] As an example, when the first timer expires, the first timer is indicated to expire to a higher layer; when the first timer expires from a lower layer, if the first process is in progress, the RRC_CONNECTED is maintained.

[0391] As one embodiment, when the first timer expires, if the first process is in progress, the first timer is instructed to expire and then passed on to a higher layer. When the higher layer receives notification of the first timer's expiration from the lower layer, if the first process is in progress, the RRC_CONNECTED setting is maintained.

[0404] As an example, when the first timer reaches the first value and the first process is in progress, the lower layer does not indicate that the first timer has expired to the higher layer. Instead, the lower layer maintains RRC_CONNECTED and continues to execute the first process.

[0417] This embodiment provides a further description of "if the first process is in progress, maintain the RRC_CONNECTED".

[0418] In this embodiment, the first timer expires when the time elapsed since the start or restart reaches the first value.

[0419] In this embodiment, when the first timer expires and the first process is in progress, the first node U01 is determined by a higher layer to maintain RRC_CONNCTED, while the lower layer instructs the first timer to expire to the higher layer.

[0432] Example 8

[0433] Example 8 illustrates a partial wireless signal transmission flowchart according to another embodiment of this application, as shown in the attached diagram. Figure 8 As shown.

[0434] for First node U01 In step S8100, a third information block is received, wherein the third information block configures the value of the second timer;

[0435] for Second node N02 In step S8200, the third information block is sent.

[0436] The first process includes the second timer running.

[0437] In this embodiment, the first node U01 can execute the following steps before executing step S8100: Figure 5 The steps S5100, S5101, S5102, and S5103 are shown. Specifically, in step S5100, the first node U01 receives a first information block; in step S5101, it receives a second information block; after executing step S8100, it can execute step S5102 to start or restart the first timer at RRC_CONNECTED; and in step S5103, it executes the first process.

[0438] The first information block configures a first value for a first timer. The second information block includes a first measurement configuration indicating at least one RS resource. Starting or restarting the first timer depends on a MAC SDU being sent or received.

[0439] Wherein, maintaining the RRC_CONNECTED depends on the first measurement configuration; during the time interval from the start or restart of the first timer to the elapsed time reaching the first value, the first node U01 neither receives any MACSDU nor sends any MAC SDU.

[0440] In this embodiment, the first node U01 can execute the following steps before executing step S8100: Figure 5The steps S5100, S5101, S5102, and S5103 are shown. In step S5100, the first node U01 receives the first information block. Then, the first node U01 executes step S5101, which includes step S8100, receiving the second and third information blocks. Afterwards, step S5102 can be executed to start or restart the first timer at RRC_CONNECTED; and step S5103 executes the first process.

[0441] In this embodiment, the second node N02 is the maintenance base station of the first node U01.

[0442] In this embodiment, the first process is unrelated to whether the first timer reaches the first value.

[0443] In this embodiment, whether the first process has ended is determined by the second timer.

[0444] As an example, the second information block and the third information block belong to the same RRC message.

[0445] As one embodiment, the second information block includes the third information block.

[0446] As one embodiment, the first process includes performing a measurement based on the first measurement configuration; or, the first process is to perform a measurement based on the first measurement configuration.

[0447] As one embodiment, the first process includes performing a measurement based on any one of a plurality of measurement configurations; wherein the second information block includes the plurality of measurement configurations, and the first measurement configuration is any one of the plurality of measurement configurations.

[0448] As a sub-example, the plurality of measurement configurations include measurement configurations for data collection only for the UE-side model.

[0449] As a sub-example, the plurality of measurement configurations include measurement configurations for data collection only for the network-side model.

[0450] As a sub-example, the plurality of measurement configurations include measurement configurations for data collection for the UE-side model and measurement configurations for data collection for the network-side model.

[0451] As an example, during the operation of the second timer, a measurement is performed based on the first measurement configuration.

[0452] As one example, the second timer is a MAC sublayer.

[0453] As one embodiment, the second timer is an RRC sublayer.

[0454] As one embodiment, the second timer starts when the second information block is received. In specific implementation, the value of the second timer is predefined, pre-configured, or configured by the second information block, in which case the second information block includes the third information block.

[0455] As a sub-implementation, the second information block indicates the start of a measurement based on the first measurement configuration.

[0456] As a variation, the second timer is started upon receiving a value configured for the second timer. Specifically, the value of the second timer is configured via the third information block; or, the value of the second timer is configured via a second information block including the third information block.

[0457] As an example, when a signaling is received, the second timer is started; the second information block belongs to an RRC message, while the signaling does not belong to the RRC message.

[0458] As a sub-implementation, the signaling and the second information block belong to two different RRC messages.

[0459] As a sub-example, the signaling is a MAC CE.

[0460] As a sub-implementation, the signaling is a DCI.

[0461] As a sub-implementation, the signaling instruction initiates the execution of a measurement based on the first measurement configuration.

[0462] As an example, the second timer is stopped when another signaling is received.

[0463] As a sub-implementation, the other signaling instruction stops performing measurements based on the first measurement configuration.

[0464] As an example, when the first node detects an RLF, the second timer is stopped.

[0465] As an example, the second timer is stopped when a cell handover is performed.

[0466] As an example, the second timer being running means that the second timer is started and has not been stopped and has not expired.

[0467] As one example, the first process not being performed includes the second timer not running.

[0468] As one embodiment, the first process includes performing measurements based on the first measurement configuration, and the second timer is running.

[0469] As an example, "the first process is in progress" means that the second timer is running, and "the first process is not in progress" means that the second timer is not running.

[0470] As one embodiment, the first process includes the second timer running, and the first process also includes a specified time during which the second timer is not running.

[0471] As one example, the specified time during which the second timer is not running includes at least a portion of the time before the second timer starts.

[0472] As an example, the specified time during which the second timer is not running includes the time during which the second timer is paused.

[0473] As an example, when the second timer is configured, the statement "maintaining RRC_CONNECTED when the time elapsed since the start or restart of the first timer reaches the first value" is true.

[0474] As a sub-implementation, if the second timer is not configured, when the time elapsed since the start or restart of the first timer reaches the first value, the process enters RRC_IDLE regardless of whether the first process is in progress.

[0475] As a sub-implementation, if the second timer is not configured, when the time elapsed since the start or restart of the first timer reaches the first value, if the first process is in progress, entering RRC_IDLE includes stopping the measurement based on the first measurement configuration.

[0476] about Figure 8 For a detailed description, please refer to the appendix. Figure 1 See Figure 7 for details.

[0478] Example 9 illustrates another portion of a wireless signal transmission process according to an embodiment of this application. This embodiment may be... Figure 1 , Figure 5 , Figure 8 A continuation of the execution of any of the flowcharts shown.

[0479] for First node U01 In step S9100, when the first timer expires, the first node U01 enters the RRC_IDLE.

[0480] In Example 9, the expiration of the first timer depends on the time elapsed since the start or restart of the first timer reaching a second value, and the first node neither receives nor sends any MAC SDU from the start or restart of the first timer until the first timer expires.

[0481] In this embodiment, the first value and the second value are different.

[0482] As an example, the first value is less than the second value.

[0483] In this embodiment, the first value and the second value are different, and the second value is predefined or pre-configured. In specific implementation, the second value is greater than the first value.

[0484] In this embodiment, the first value and the second value are different. The second value is configured by the second information block to indicate the expiration value of the first timer. In specific implementation, the second value is greater than the first value.
